Question

I have some problems trying to update components of surface elements. I dont know if my approach to the problem is wrong, since I’m new to the topic.

My point is represented by the following diagram

According to the option that is selected in the menu, load different user controls as only child of StackPanel but i’m habing problems for update the Listview from loaded user controls, example: when I save a new item I need to recharge the list of items in the ListView

MVVM would be a good pattern here. If you have a problem passing data between controls – why not introduce them on top of unified data layer? Consider this:

Three radio buttons in your Menu, each one’s IsChecked property bound to Visibility property of your respective UserControl.

StackPanel holding all three UserControls

ListView bound to ViewModel’s List<Item>

Each of your UserControls bound to ListView.SelectedItem: one of them using TextBlock for read-only, one using TextBox for editing. Third one would create new item in your List<Item>. You would have to create ItemTemplate for each or create one UserControl (since they look very much alike) and use DataTemplateSelector.

If you’re not familiar with MVVM here is a good start. You can also use one of the existing frameworks like MVVM Light
